The Election Commission (EC) threw open the Electronic Voting Machine challenge at its headquarters at Nirvachan Sadan in New Delhi on Saturday, June 3. The EC is holding the hackathon challenge in light of the allegations made by some political parties, including the Aam Aadmi Party (AAP), that EVM-tampering was used by the Bharatiya Janata Party (BJP) to win the elections.
